Hi all,

I just replaced 2 brushes (per a video) and the tiny tab that holds the brush/spring in place doesn’t hold. The brush goes back in place just fine.

Can I just install it with out the tiny holding tab holding the brush?

Thanks….

Are they paint brushes or wire brushes. It might matter.

Carbon brushes for a table saw.

Brushes work by having that spring press the carbon against the motor. So you definitely need the part that holds the tab to be held at the right depth. I think the part with the tab is what completes the circuit so you really need that to have a solid connection too. It sounds like you got the wrong brushes or aren’t connecting the tab right. Pictures, brand/model number, etc might help.

I would consider upgrading away from a table saw with a brushed motor… That being said, Tim is correct on this.
